Hardware problems

About this topic

This topic lists possible hardware problems, the causes of the problems, and ways to 
resolve the problems. If you are still experiencing problems with the BenchCel 
Microplate Handler after trying the solutions, contact Agilent Technical Support.

Hardware problems

Problem

Cause

Solution

The BenchCel 
Microplate Handler 
does not turn on.

Your lab does not meet the 
electrical requirements.

Make sure your lab meets the electrical 
requirements. See 

“Verifying laboratory 

requirements” on page 37

.

The BenchCel Microplate Handler 
is not connected to the power 
source.

Connect the BenchCel Microplate Handler to 
the power source. See 

“Connecting the power 

source” on page 50

.

The fuse is blown.

See 

“Replacing the fuse” on page 134

.

A bad fuse could be indicative of other 
problems. If the fuse blows again, contact 
Agilent Technical Support.

A hissing sound can 
be heard.

A leak is present in the air 
connection or inside the device.

Check the air connections at the back of the 
device and at the source (house, cylinder, or 
pump). 
If the connections look fine, the leak might be 
inside the device. Contact Agilent Technical 
Support.

Oil is present in the 
stacker head.

The compressed air is not from an 
oil-free compressor and oil has 
leaked into the BenchCel 
Microplate Handler.

Contact Agilent Technical Support.

The microplate drops 
from the robot 
grippers.

The labware definition for the 
microplate type might contain 
incorrect information.

Check the following in the labware definition: 
Stacker gripper offset, Robot gripper offset, 
Stacking thickness, Plate thickness, Sensor 
intensity, and the Plate presence threshold.
To check or correct these values, open 
BenchCel Diagnostics. On the 

Controls

 page, 

click the 

Labware

 tab.

Note: 

In the Plate offsets (mm) area, type 8 in 

the Robot gripper offset and the Stacker 

gripper offset boxes. The recommended 

offset for most labware is 8 mm.
If the problem persists, contact Agilent 
Technical Support.
